JEROME F. MCOALL, OF FRANKFORD, PENNSYLVANIA.

PAPER BOX.

Specification of Letters Patent.

Patented March 23, 1909.

Application filed April 5, 1907. Serial No. 366,486.

To all whom it may concern:

Be it known that I, JEROME F. MoOALL, a citizen of the United States,and resident of Frankford, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Im rovements in PaperBoxes, of which the follbwing is a specification.

The principal object of the present invention is to provide a fastenerfor the corners of knock-down boxes and their lids, which shall not onlybe comparatively inexpensive to make and apply but which shall alsoperform the double function of firmly holding the folds at the corner ofthe boxes and lids to place, and of protecting the edge of the corners.

Other objects of the invention will appear from the followingdescription and the invention itself will be first described and afterward claimed.

The nature, characteristic features and scope of the invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof, and in which Figure1, is a perspective view of a fastener detached. Fig. 2, is a top orplan view showing a corner of a box or lid in knock-down osition withthe fastener applied thereto. ig. 3, is a sectional view taken on theline 3-3 of Fig. 1. Fig. 4, is an elevational view of the corner of abox or lid showing the fastener in operative position, and Fig. 5, is anelevational view of the inside of the corner of a box or lid, showingthe fastener.

In the drawings 1, is the fastener and it may advantageously be made ofmetal capable of being easily bent and composed of sufficient strengthfor the urpose. The fastener consists of a folded s ank 2, and aprojecting tongue 3. The shank is folded at the edge 4 and is open atits other three edges, and if desired the corners of the tongue 3, maybe beveled off as at 5 or otherwise shaped. When the box art is knockeddown, that part of it whic consists of two plies is inserted into theshank 2, as shown in Fig. 2, and the tongue 3 may reject as shown inthat figure or it may be ent down onto the shank for convenience inpacking. When the box part is placed in position the tongue 3, is bentdown over three plies of the box part as shown in Fig. 5, it beingunderstood that the box part folds up along the line 6 in the ordinaryand well understood manner.

Referring to Fig. 2, the parts a, a of the box are one-ply and the partsI), 1), b are two-ply. The edge of the top ply I), b, is shown at c, c.f, is the edge of the infolded side.

To set up the box the top ply at b, is turned up into vertical positionas is also the single ply a the former being turned in and the latterout. The fold at 6, lies inside the box as shown in Fig. 5, and thesingle ply at b", separated by the creasing or folding is made to faceand lie against the part I), thus bringing the three plies together atthe corner when the box is set up.

From the foregoing description it is evident that when assembled theshank 2 clasps two plies of the corner and the tongue folds over threeplies of the corner so that the corner as a whole is not only reinforcedand made strong, but is also protected by the portion 4 of the shank.

Having thus described the nature and objects of my invention, what Iclaim as new and desire to secure by Letters Patent is 1. Thecombination of a knock down box part having at its corner acreased'portion which brings three plies together, and a fasteningconsisting of a centrally folded shank constituting a corner protectorbrace and havin straight folds clamping the two outside pl ies betweenthem and one of said folds having normally projecting from its end astraight flat top adapted to be turned in toward the other fold andclamp the third ply between said fold and tongue, substantially asdescribed.

2. A fastener for boxes comprising a metal shank folded alongapproximately its center line and forming two flat straight folds andone of said folds having a straight flat tongue projecting from its endin the same plane with it, substantially as described.

In testimony whereof I have hereunto signed my name.
